77 Application filed January 25, 1919, Serial No. 273,070.

To all whom it may concern:

Be it known that I, PATRICK J. FITZGER- ALD, a citizen of the United States, residing at Torrington, in the county of Litchfield, State of Connecticut, have invented certain new and useful Improvements in Massageof which the following is' a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

My invention relates to new and useful improvements in massage vibrators.

The object of the invention is to provide a massage vibrator wherein spring means are provided for drawing the spring carrying the armature closer to or allowing it to recede from the magnets, whereby the degree of vibratory movement of the arm carrying the applicator may be varied.

Another object of the invention is to provide adjusting means in such a position that it maybe readily adjusted without stopping or removing the vibrator from the face or the surface being massaged, and at the same time'provide a simple, cheap and effec: tive structure having certain details of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawings:

Figure 1 is a side elevation, .partly in section, of my improved massage vibrator;

Fig. 2 is a perspective view of the front plate removed, looking from the inside, parts of the spring tension adjusting means in their separated relation.

Referring now 'to the. drawings, 1 represents the body portion of my improved vi-- brator, which, as shown, is of a cylindrical form, but which may be of any desired shape. Said body portion closed by the integral'head 2, and, as shown, has a central outwardly pressed portion 3, to which is bolted M4 the support 5- for the magnets 6. Rigidly secured to the periphery of the cylindrical body portion is a handle through which pass the wires 8 and 9, which are connected to the 'magnets 6, as indicated at 10 and through which the electrical current passes for energizing the magnets. As is understood, these magnets are adapted to be energized intermittently byan alter: nating current,.so as to cause a rapid vibraheld thereon by has one end.

7 which is of a hollow form and.

tion of the armature, hereinafter-more fully described.

The magnets, as will be understood, are spaced some distance need no further description. The front end of-the body portion lis closed by a head 11, means of a coil spring, so that the same may any part of the interior mechanism. The head 11, as shown in Fig. 1 of the drawing, is provided-with a central outwardly pressed portion 12 to allow for the movement armature, as clearly shown inFig. 1. Secured to the innerface of the head 11-, by means of'bolts 13, is a spring 14, which ex tends inwardly and terminates at a point approximately at the center of the head. The outer end of the arm is bent outwardly to bring it slightly within thev outwardly pressed portion 12, so as to allowspace'for the armature 15. TlllS armature, as shown,

is of an elongated form, and is secured to.

the end of the spring 14:, and extends at. right angles thereto, as clearly shown in Fig.2 of the. drawings. his armature being of an elongated form extends o posite the endsof both magnets and is energized Patented. a... 6, i920.

be removed for repairing ofthe thereby, as will be understood by those skilled in the art.

Secured to the end of the spring 14 is an arm 16, which extends outwardly through an opening 17 in the head 11. This arm is preferably in the form of a tube, being inter: nally threaded at its inner end, as indicatat 18, and into which is screwed the screw 19,

" which passes from the inner face of' the ar mature 15 therethrough and through the spring. The outer end of the arm is provided-with a which'is screwed the applicator 21, and by this arrangement, applicators of different character may be readily The spring 14; has two slits 22,--and the metal between the slits is struck up, as indicated at 23, and into which is hookedthe hook 24 of the coil spring 25. The opposite end of the coil spring is provided with,v a.

hook into. an eye'26,'

hook 26, adapted to formed in the flattened end 27 of the threaded bolt 28. This bolt, as shown, extends out through an opening 29 in the head 2 of the body portion 1, and has a thumb nut 30 threaded portion 20, upon applied to the arm.

screwed thereon which bears against. the

outer face of the head.

From the foregoing description, it will be seen that b turning the thumb-nut 30, the bolt 28 is pass inwardly, and thus increases or decreases the tension of the spring 14, and thus changes the relative position of the spring 14 an applicator secured .to said spring and exv tending through said cover, a spring arranged within the casing and having its opposite ends connected to said leaf spring and the casing Wall opposite the cover, and means for adjusting the tension of said spring.

2. In a massage vibrator, the combination of a casing inclosing electro-magnetic means, a leaf sprlng secured to said casin with its free end extending into the field of and adapted to be vibrated by said electro-magnetic means, an apertured armature on the end of said leaf spring, an internally threadrawn outwardly, or allowed to ed tube vibratable through a hole in said caS ing, a screw passing through the apertures of said armature and leaf spring and threading into said tube, and an applicator connected to the opposite end of said tube.

3. In a massage vibrator, the combination of a casing, an electric magnet carried therein and adapted to be intermittently energized, a leaf spring secured in the casing and having its free end extending into the field of and adapted to be vibrated by said magnet, said spring having two parallel slits, and the metal between the same being struck up to form a loop, a coil spring having a hook at one end adapted to pass through the loop, a bolt having an eye in one end and through which passes a hook carried by the opposite end of the coil spring, said bolt passing through the casing,

a thumb nut on said bolt on the outside, of

the casing for varying the tension of the coil spring on the leaf spring, and an applicator carried by the leaf sprmg and extending through the casing.

n testimony whereof, I alfix my signature in the presence of two witnesses.
